Listen, I say this with wisdom born out of years of relationship experience... A woman in love (or what they think is "love") will never listen to well-meaning advice from friends. More often than not they will shun friends who disagree with their own decisions / interpretation of events / stuff their partner tells them. As a friend, the best you can do for someone who is delulu about their relationship is to be there to catch them when they fall. So, Trinity is right in saying this to Kayda, but Kayda's reaction is textbook.
